I am upgrading my m15x R2 from 240m to 460m. I ordered the new card online and was sent thermal paste with it. Does anyone know if the thermal paste below work for this graphics card in my m15x. If not, what would be the best I should use Stars 612 Copper Thermal Compound Grease Paste Tube Features: Thermal coupling of electrical / electronic device to heat sinks High Thermal Conductivity ,Low Bleed and Stable at high temperature Helps the heat dissipation from a CPU to a heatsink Specifications: Type: Copper Grease (gold color) Heat exchange (conductivity): >1.829W/m.k Thermal impedance (resistance): <0.123°C-in²/W 20% metal oxide compound
